Description

Technical Field

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figure 1 - Figure 3 As shown in the figure, an embodiment provided by the present utility model: an adjustable clamping device driven by an electric cylinder, including a placement plate 1. Both sides of the upper surface of the placement plate 1 are fixedly connected with baffles 2. The outer wall of the baffle 2 is rotatably connected with a first rotating seat 3. The outer wall of the first rotating seat 3 is fixedly connected with an electric cylinder 4. The output end of the electric cylinder 4 is fixedly connected with a second rotating seat 5. The outer wall of the second rotating seat 5 is rotatably connected with a double-hole connecting rod 6. A rotating shaft 7 is fixedly connected inside the double-hole connecting rod 6. A bearing seat 8 is arranged on the outer wall of the rotating shaft 7. One side of the outer wall of the bearing seat 8 is fixedly connected to the outer wall of the baffle 2. A fixing component is arranged inside the rotating shaft 7, and the fixing component is used for fixing the material box. A holding ring 11 is fixedly connected to the outer wall of the rotating shaft 7. A detection piece 12 is fixedly connected to the outer wall of the holding ring 11. A sensor 13 is fixedly connected to the outer wall of the baffle 2. The outer wall of the detection piece 12 is slidably connected to the inner wall of the sensor 13. The fixing component includes a first sliding rod 9. The outer wall of the first sliding rod 9 is slidably connected inside the rotating shaft 7. A blocking block 10 is fixedly connected to the outer wall of the first sliding rod 9;

[0026] Specifically, first place the material box on the upper surface of the placement plate 1, then drive the electric cylinder 4. Drive the second rotating seat 5 to move through the output end of the electric cylinder 4. Then drive one side of the double-hole connecting rod 6 to move through the movement of the second rotating seat 5, so that the double-hole connecting rod 6 rotates around the rotating shaft 7, thereby driving the rotating shaft 7 to rotate. During this process, the rotating shaft 7 is fixed on one side of the baffle 2 by the bearing seat 8 for support. Then drive the first sliding rod 9 and the holding ring 11 to rotate through the rotation of the rotating shaft 7. When the first sliding rod 9 rotates, it will drive the two side blocking blocks 10 to rotate around the first sliding rod 9. When the blocking block 10 rotates, first, the arc surface preset on one side of its outer wall can push the material box to move to the center position of the placement plate 1 to achieve preliminary positioning. Then, the rectangular plate on the other side of the outer wall of the blocking block 10 presses down on the material box to fix it, realizing the fixation of the material box. At the same time, the holding ring 11 will drive the detection piece 12 to rotate. When the blocking block 10 fixes the material box, the detection piece 12 just moves to the inner wall of the sensor 13 with the model: Omron D4N. At this time, the sensor 13 operates and stops the electric cylinder 4 to achieve an emergency stop.

[0027] Referring to Figure 3 -Figure 5 Inside the first sliding rod 9, there is an installation hole 24. On the outer wall of the rotating shaft 7, a fixed ring 14 is fixedly connected. Inside the inner wall of the fixed ring 14, a rotating ring 15 is rotatably connected. Inside the inner wall of the rotating ring 15, a rotating plate 16 is fixedly connected. The outer wall of the rotating plate 16 is rotatably connected inside the fixed ring 14. Inside the rotating plate 16, an arc-shaped sliding groove 17 is provided. Inside the rotating plate 16, a sliding shaft 18 is slidably connected. One end of the sliding shaft 18 is fixedly connected with a limiting ring 19, and the other end of the sliding shaft 18 is fixedly connected with a clamping block 20. The outer wall of the clamping block 20 is slidably connected inside the fixed ring 14 and the first sliding rod 9. On one side of the outer wall of the clamping block 20, a limiting plate 21 is fixedly connected. On the other side of the outer wall of the clamping block 20, a second sliding rod 22 is fixedly connected. A spring 23 is sleeved on the outer wall of the second sliding rod 22. One end of the spring 23 is fixedly connected to the outer wall of the clamping block 20, and the other end of the spring 23 is fixedly connected inside the fixed ring 14;

[0028] Specifically, drive the rotating ring 15 to rotate on the inner wall of the fixed ring 14, thereby driving the rotating plate 16 to rotate inside the fixed ring 14. While the rotating plate 16 is rotating, the sliding shaft 18 will slide in the arc-shaped sliding groove 17 preset inside the rotating plate 16, and then the sliding shaft 18 will linearly move inside the fixed ring 14. Then, through the movement of the sliding shaft 18, the clamping block 20 slides inside the fixed ring 14 and the first sliding rod 9. When the clamping block 20 completely moves inside the fixed ring 14, the first sliding rod 9 is no longer restricted, and at the same time, the spring 23 contracts. Then, the first sliding rod 9 can be pulled to slide inside the rotating shaft 7 to adjust the position of the blocking block 10 so that it can be applied to material boxes of different widths. When the first sliding rod 9 moves to a suitable position, release the rotating ring 15. At this time, the spring 23 rebounds without being stressed, thereby pushing the clamping block 20 to move back inside the first sliding rod 9 to fix it.

[0029] Working principle: When the adjustable clamping device driven by the electric cylinder needs to be used, first place the material box on the placing plate 1. Then, push the second rotating seat 5 to move through the electric cylinder 4, thereby driving one end of the double-hole connecting rod 6 to move, making the double-hole connecting rod 6 rotate around the rotating shaft 7. The rotating shaft 7 is fixed on one side of the baffle 2 under the support of the bearing seat 8. The rotation of the rotating shaft 7 drives the first sliding rod 9 and the holding ring 11 to rotate. The rotation of the first sliding rod 9 makes the blocking block 10 rotate around its center, and the arc-shaped surface pushes the material box to be centered. At the same time, the rectangular plate presses down to fix the material box. At the same time, the rotation of the holding ring 11 makes the detection piece 12 move to the inner wall of the Omron D4N type sensor 13, triggering the sensor 13 to stop the electric cylinder 4 to achieve the emergency stop function;

[0030] In addition, by driving the rotating ring 15 to rotate on the inner wall of the fixed ring 14, the rotating plate 16 is driven to rotate, and the sliding shaft 18 slides in the arc-shaped chute 17, realizing the linear movement of the sliding shaft 18 inside the fixed ring 14. The movement of the sliding shaft 18 enables the clamping block 20 to slide within the fixed ring 14 and the first sliding rod 9. When the clamping block 20 completely enters the fixed ring 14, the restriction on the first sliding rod 9 is released, and the spring 23 contracts. At this time, the first sliding rod 9 can be pulled to slide inside the rotating shaft 7 to adjust the position of the blocking block 10 to adapt to material boxes of different widths. After the first sliding rod 9 is adjusted to an appropriate position, the rotating ring 15 is released, and the spring 23 rebounds to push the clamping block 20 to fix the first sliding rod 9 again, completing the position adjustment. Such a design realizes the flexible adjustment of the clamping device and ensures the stable clamping of the material box.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
